Galaxy Tab 3 won't turn on
My tab 3 did a software update, and ever since, has been completely unresponsive (no lights, no screen backlight, no vibration when plugging something in, etc). The only kind of response I can get is if plugged into the computer, the computer will recognize it (When plugging in the USB, the computer makes the hardware connected sound).
Here's what I've tried:
- Every possible combination of holding buttons
- Different chargers (2A, 1.5A, 1A, 800mA, 400mA), and different cords, including the factory charger/cord
- Took the back off, unplugged the battery and plugged it back in
- Plugged it in to multiple chargers with the battery disconnected
- Brought it to Sprint repair center, they said to send it to Samsung
- Sent to Samsung for warranty repair (they declined to fix it because of a microscopic chip on the corner of the device) (The tablet came with the chip and worked great for a year - it's not the cause of the problem)
So I was thinking, my next step might be to buy a new battery.
Is there any way to test the current battery? There are 5 leads (two black, two red, and a blue).
Am I wasting my time with the battery? Should the unit have powered up without the battery installed?
My other thought is the charging port. Maybe my battery is dead, and it can't be charged. I blew out the charging port. The cable is not loose in the connector. I tried wiggling and holding it in every direction imaginable, still no response.
Any other ideas??
